Tube Amp Archive

Hello I'm wondering whether I can occasionally use a high quality ~50W 4kohm OT with 4x6L6WGB if I wanted to? If I was running 4x6L6 I would be running 8ohm speakers (2x16ohm in parallel) into the 16ohm tap (tubes would see 2kohm) and I would be using power scaling. The OT would never actually see 8...

thanks Steve What is the best way to design by build to accomodate 6V6's higher impedance load? On PT, I suppose a 40W PT and OT accomodates 6L6's but I'm more focused on optimising tone around 15-20W (which is more than enough) Would 100mA be enough for what I'm looking to build? This one seems to ...

Ok thanks

Do you mean the first one (120mA) or the beefed up 5f6-a tranny? I'm not sure I would want an oversized PT Stevem - have you tried to experiment with variations of 5f6-a and ended up concluding only really sounds good with original big bottle power section + 2ohm 4x10? Just trying to read between th...

The cab I have is actually 8ohm. I'm planning to use a 4/8/16 ohm OT - 20W Classictone Fender-style

Biggest question to me is does PT have enough power though

That also an excellent point Was planning to use this http://www.classictone.net/40-18028.html http://www.classictone.net/40-18028.pdf But does it have enough juice to power all these tubes? - Rectifier (GZ34 or 5A4GB) - 2x6V6GT - 2x12AT7 - 2x12AY7 - 1x12AY7 Otherwise this definitely has all the pow...

That's pretty much exactly what I'm planning to build! thanks

I'll try both mixing resistors + 3-input LTIP and see what sounds best

Hi
No plans to gig it, just home use - will go through a 2x10 cab with NOS AC10-type ELACS (at least for now)
Also why I'm going for 6V6's
thanks!

You're absolutely right - it won't be a 5f6-a, just a variation. I do plan to have a presence control though! I was going to build 2 single-channel amps with a relatively similar 6V6 power section - a single channel Deluxe Reverb + a variation of a 5f6-a. Conscious neither will sound exactly like th...

Ok, thanks

I'm told separately that 3-input LTP actually seems to work as well. Relatively easy to try both

Based on your experience, does having 2 preamps / channels into 1 power section have a negative impact on tone vs. having single channel amps?

Hello, I'm getting started on a Deluxe Reverb variation (single channel, reverb - no trem, normal 6V6 power section). Then thought that I could consider adding 2 tubes (PT would have enough juice) and build a 5f6-a preamp as a new channel. Not entirely sure how to combine the 2 channels though: - LT...
